I'm pasting it here as they typically delete the beta forums after release.

They come from the target. They travel at 25y/s to a random point 2-5yd from a point 15yd to the front right or front left (alternating) of the target.At that point, they spawn and are active to be picked up, and are triggered when you get within 6yd of them.

There seems to be a bug at the moment which prevents Demon Hunters from picking up souls while mounted. The soul will disappear, and neither the heal nor the 20% dmg buff from Demon souls will be applied. So stay dismounted if you want those heals before continuing on your quest. The bug has been fixed and souls now heal while mounted aswell.

If you're like me and wondering why the 20% damage bonus doesn't always activate, the soul fragment needs to come from a DEMON mob. It's quite subtle in the tooltip, "consuming a demon's soul".

I don't know if it's just me but since BFA I didn't even see a single demon type mob, literally voiding the 20% increased damage bonus.. :(
